[0048] 400-Bogie. Detailed Implementation

[0049] After a period of operation, rail vehicles require maintenance, and the bogie is a key component of this process. A bogie is an independent running structure consisting of two or more pairs of wheelsets connected by a frame or other device, capable of rotating relative to the car body, and equipped with springs and other components. The bogie supports the car body to bear various loads and transfers these loads to the wheelsets. Simultaneously, the bogie ensures even axle load distribution, guaranteeing stable car movement.

[0050] In the manufacturing and maintenance of rail vehicles, the bogie turntable, as a core process equipment, is mainly used on the new manufacturing production line and the process maintenance line for steering the bogie and wheelset when they run on the track, realizing their track switching and line switching. The track switching and line switching process mainly includes two operations: rotation and parking. The process requirements for the operation are: the speed is stable during rotation and the bogie is in the parking state; when parking, the turntable is accurately aligned and firmly locked.

[0051] In some embodiments of the related technology, the slewing device of the bogie turntable has no drive mechanism, and the rotation parking and parking locking need to be completed manually, which is labor-intensive, the track switching process is cumbersome, the parking alignment accuracy is low, and the maintenance efficiency of the bogie is low. In some embodiments, a drive structure such as a motor is added to the slewing device, which reduces the labor intensity to some extent. However, parking still adopts the method of manually placing the iron shoe. There is no connection between the iron shoe and the turntable body, and there is no self-locking structure, which poses a risk of slippage.

[0052] Based on the aforementioned technical problems, this application provides a bogie turntable. By setting a slewing component, the turntable body can be rotated in the circumferential direction. By setting a parking component, the limiting end protrudes from the top surface of the turntable body. The limiting end can limit the bogie during the rotation of the turntable body, avoiding the problem of relative displacement between the bogie and the turntable body during rotation. This allows the bogie to be parked on the turntable body, eliminating the need for manual installation of parking shoes. This improves the automation level of the maintenance process, reduces manual labor intensity, reduces the number of operators, and improves operational safety.

[0053] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Figure 3 A schematic diagram of the structure of the bogie turntable located in the foundation pit according to an embodiment of this application. Figure 1 , Figure 4 A schematic diagram of the structure of the bogie turntable located in the foundation pit according to an embodiment of this application. Figure 2 .

[0055] Reference Figures 1 to 4 As shown, this application embodiment provides a bogie turntable 100 located in the pit 200 of the maintenance workshop 300. A bogie 400 to be maintained is placed on the bogie turntable 100. A first track 310 for the bogie 400 to be maintained to rotate into is provided in the maintenance workshop 300.

[0056] For example, refer to Figure 1 As shown, the maintenance workshop 300 has a first track 310, the bogie 400 has wheelsets, and the bogie turntable 100 has a second track 111. During actual maintenance, the wheelsets of the bogie 400 are located in the second track 111, and the bogie turntable 100 rotates in the circumferential direction. When the second track 111 and the first track 310 are aligned, the bogie turntable 100 stops rotating, and the bogie 400 rotates into one of the first tracks 310.

[0057] Among them, reference Figure 2 When the second track 111 and the first track 310 are in the aligned state, "aligned" means that the first track 310 and the second track can be connected together at a certain position.

[0058] Continue to refer to Figure 3 and Figure 4 As shown, the bogie turntable 100 is located in the foundation pit 200 of the maintenance workshop 300. The foundation pit 200 is an excavated pit dug at the foundation design location according to the foundation elevation and foundation plane dimensions. Exemplarily, in this embodiment of the application, the foundation pit 200 is a circular foundation pit with steps 210.

[0059] The following will refer to Figures 5 to 8The structure of the bogie turntable is described below:

[0060] Figure 5 A schematic diagram of the front structure of the bogie turntable provided in the embodiments of this application. Figure 1 , Figure 6 This is a schematic diagram of the back structure of the bogie turntable provided in an embodiment of this application. Figure 7 This is a schematic diagram of the parking assembly, support wheel set, and slewing assembly of the bogie turntable provided in an embodiment of this application. Figure 8 This is a schematic diagram of the parking assembly of the bogie turntable provided in an embodiment of this application.

[0061] Reference Figures 5 to 8 As shown, the bogie turntable 100 may include a turntable body 110, a slewing assembly 120, a parking assembly 130, a locking assembly 140, and a controller. The top surface 113 of the turntable body is provided with a second track 111.

[0062] For example, the second track 111 can be a grid-shaped structure.

[0063] The first end of the rotary assembly 120 is connected to the turntable body 110, and the second end of the rotary assembly 120 is connected to the pit 200. The rotary assembly 120 and the turntable body 110 are electrically connected. For example, the rotary assembly 120 and the turntable body 110 can be electrically connected via a wired connection, or they can be electrically connected via a wireless connection. This embodiment does not further limit the connection.

[0064] The first end of the parking assembly 130 is connected to the bottom surface 114 of the turntable body, and the second end of the parking assembly 130 is connected to the pit 200. The parking assembly 130 has a limiting end that protrudes from the top surface 113 of the turntable body. The first end of the locking assembly 140 is located on the side close to the turntable body 110, and the second end of the locking assembly 140 is connected to the pit 200.

[0065] For example, the connection methods of the slewing assembly 120 and the pit 200, the locking assembly 140 and the pit 200, and the parking assembly 130 and the pit 200 are not further limited. For example, they can be connected by snap-fit, welding, etc. The specific connection can be made according to the actual working conditions.

[0066] The controller is electrically connected to the slewing assembly 120 and the locking assembly 140 respectively. For example, the controller and the slewing assembly 120 and the controller and the locking assembly 140 can be electrically connected by wire or wireless means.

[0067] In this embodiment, the communication between the controller and the slewing assembly 120, and between the controller and the locking assembly 140, is mainly illustrated by wireless communication. For example, wireless communication modules such as WiFi (Wireless Fidelity) and 5G (5th Generation Mobile Communication Technology) can be used to transmit signals, remotely control the slewing assembly 120 to drive the rotation of the turntable body 110, and remotely control the locking assembly 140 and the locking of the turntable body 110. One-button operation can realize the reduction or even unmanned operation of the bogie 400 during the track switching process, and can help realize the intelligence and automation of the bogie 400.

[0068] For example, the turntable body 110 can be made of steel.

[0069] The track-shifting process of the bogie turntable 100 and bogie 400 provided in this embodiment is as follows:

[0070] The controller controls the rotary assembly 120 to drive the turntable body 110 to rotate along the circumferential direction of the turntable body 110. For example, the circumferential direction of the turntable body 110 can be referred to... Figure 5 As indicated by the middle arrow A, specifically, it can rotate counterclockwise along the circumferential direction of the turntable body 110, or it can rotate clockwise along the circumferential direction of the turntable body 110. This application embodiment does not further limit this.

[0071] When the turntable body 110 rotates to the point where the second track 111 and the first track 310 are aligned, the turntable body 110 stops rotating. The parking assembly 130 drives the limiting end to retract from the top surface 113 of the turntable body to the bottom surface 114 of the turntable body. At the same time, the controller controls the locking assembly 140 to drive the first end to lock in the turntable body 110, and the turntable body 110 is in a locked state. The bogie 400 rotates into the first track 310, thus successfully completing the track rotation of the bogie 400.

[0072] Therefore, the bogie turntable 100 provided in this embodiment, by including the rotation component 120, facilitates the circumferential rotation of the turntable body 110. By including the parking component 130, with a limiting end protruding from the top surface 113 of the turntable body, the limiting end can limit the bogie 400 during rotation on the turntable body 110, preventing relative displacement between the bogie 400 and the turntable body 110 during rotation. This achieves higher reliability of parking the bogie 400, eliminating the need for manual installation of wheel chocks, improving automation during maintenance, reducing manual labor intensity, decreasing the number of personnel, and enhancing operational safety. The locking component 140 can lock the turntable body 110 when it stops rotating, preventing the risk of slippage and ensuring smooth track transition of the bogie 400, guaranteeing its smooth and efficient passage.

[0073] Figure 9 Schematic diagram of the parking assembly provided in the embodiments of this application Figure 1 , Figure 10 Schematic diagram of the parking assembly provided in the embodiments of this application Figure 2 .

[0074] The structure of the parking assembly is described below:

[0075] Reference Figure 9 and Figure 10 As shown, the parking assembly 130 may include a parking actuator 131, a parking drive 132, and a parking mount 133. The parking mount 133 is connected to the pit 200. The parking drive 132 is disposed on the parking mount 133. The parking actuator 131 is connected to the bottom surface 114 of the turntable body. The first end of the parking assembly 130 is the end of the parking actuator 131 connected to the turntable body 110, and the second end of the parking assembly 130 is the end of the parking mount 133 connected to the pit 200.

[0076] For example, the parking mount 133 can be made of steel.

[0077] Specifically, refer to Figure 9 and Figure 10As shown, the parking actuator 131 may include a stop block 1311, a spring 1312, a retaining plate 1313, a connecting rod 1314, and a connecting block 1315. The retaining plate 1313 is disposed between the stop block 1311 and the connecting block 1315. The stop block 1311 is located on the side of the retaining plate 1313 closer to the turntable body 110, and the connecting block 1315 is located on the side of the retaining plate 1313 away from the turntable body 110. The retaining plate 1313 is connected to the bottom surface 114 of the turntable body, and the stop block 1311 is a limiting end.

[0078] Spring 1312 is located between stop block 1311 and clamping plate 1313. Both ends of spring 1312 abut against stop block 1311 and clamping plate 1313 respectively. Connecting rod 1314 passes through clamping plate 1313. Both ends of connecting rod 1314 are connected to stop block 1311 and connecting block 1315 respectively. Connecting rod 1314 located between stop block 1311 and clamping plate 1313 is sleeved on the outside of spring 1312.

[0079] Specifically, the parking drive component 132 may include a drive motor 1321 and a connecting plate 1322. The drive motor 1321 is mounted on the parking mounting base 133, and the connecting plate 1322 is mounted on the side of the drive motor 1321 away from the parking mounting base 133. The drive motor 1321 and the connecting plate 1322 are electrically connected.

[0080] It should be noted that the parking assembly 130 in this embodiment of the application has a split structure. For example, the parking assembly 130 in this embodiment of the application adopts an upper and lower fastening method, which facilitates installation and maintenance operations, reduces the difficulty of multi-directional adjustment, and reduces the workload of installation and maintenance.

[0081] The movement process of the parking assembly 130 is explained as follows:

[0082] During the rotation of the turntable body 110, the stop block 1311 protrudes from the top surface 113 of the turntable body (see details). Figure 5 As shown), specifically, the stop 1311 protruding from the top surface 113 of the turntable body is located in the second track 111, which helps to limit the wheelset of the bogie 400 located in the first track 310.

[0083] Specifically, a rim groove 112 may be provided on the turntable body 110, and the stop block 1311 protrudes from the top surface 113 of the turntable body through the rim groove 112. The groove depth, groove width, groove diameter, etc. of the rim groove 112 are not further limited, and can be set according to actual needs.

[0084] Spring 1312 is located between the locking plate 1313 and the stop block 1311, and spring 1312 is in an elastically compressed state between the locking plate 1313 and the stop block 1311. This arrangement helps to ensure that the stop block 1311 is in the extended state under the elastic action of spring 1312. The locking plate 1313 is connected to the bottom surface 114 of the turntable body, which helps to ensure that the parking actuator 131 always rotates and stops with the turntable body 110. The connecting rod 1314 and the connecting block 1315 are integrated and can jointly transmit the tension applied by the parking drive 132 to the parking actuator 131.

[0085] It should be noted that during the rotation of the turntable body 110, the parking drive component 132 and the parking actuator 131 are separate structures. That is to say, during this process, the parking drive component 132 and the parking actuator 131 have no connection relationship. With this setting, the parking drive component 132 will not interfere with the rotation of the parking actuator 131. In addition, the parking drive component 132 can be powered independently, which helps to avoid the installation and maintenance work caused by using conductive slip rings, thereby helping to avoid the resulting failure risks and costs.

[0086] Furthermore, the connection method between the connecting rod 1314 and the stop block 1311, and between the connecting rod 1314 and the connecting block 1315, is not further limited. For example, the connecting rod 1314 and the stop block 1311, and between the connecting rod 1314 and the connecting block 1315, can be connected by bolts. Alternatively, the connecting rod 1314 and the stop block 1311, and between the connecting rod 1314 and the connecting block 1315, can be connected by other methods. The specific method can be set according to the actual situation.

[0087] When the turntable body 110 rotates to the point where the second track 111 and the first track 310 are aligned, the turntable body 110 stops rotating. At this time, the drive motor 1321 drives the connecting plate 1322 to move in the direction close to the turntable body 110. The connecting plate 1322 is engaged in the connecting block 1315. Specifically, the connecting block 1315 may have a slot 1316. The connecting plate 1322 is engaged in the slot 1316. Then, the drive motor 1321 drives the connecting plate 1322 to move in the direction away from the turntable body 110. The connecting plate 1322 drives the parking actuator 131 to move in the direction away from the turntable body 110. The limiting end retracts from the top surface 113 of the turntable body to the bottom surface 114 of the turntable body, and the bogie 400 rotates into the first track 310.

[0088] It should be noted that the first track 310 here refers to the track into which the bogie 400 is rotated for maintenance. For example, the slot 1316 can be a C-shaped slot.

[0089] Figure 11This is a schematic diagram of the locking assembly of the bogie turntable provided in an embodiment of this application.

[0090] The structure of the locking component is described below:

[0091] Reference Figure 11 As shown, the locking assembly 140 may include a locking motor 141, a pin 142, and a locking mounting base 143. The locking mounting base 143 is connected to the pit 200. For example, the locking mounting base 143 and the pit 200 may be connected by a fixing method such as bolts. The locking motor 141 is disposed on the locking mounting base 143, and the pin 142 is disposed on the side of the locking motor 141 opposite to the locking mounting base 143.

[0092] It should be noted that the locking component 140 in this embodiment can be a split structure. For example, the locking component 140 in this embodiment adopts an upper and lower fastening method, which facilitates installation and maintenance, reduces the difficulty of multi-directional adjustments, and reduces the workload of installation and maintenance. In addition, the locking component 140 does not require slotting on the side of the foundation pit 200 during installation, which helps to save space and reduce infrastructure costs.

[0093] The locking process of the locking component 140 is as follows: When the second track 111 and the first track 310 are aligned, the locking motor 141 drives the pin 142 to move in the direction close to the turntable body 110. The pin 142 is engaged in the turntable body 110, thus locking the turntable body 110. Specifically, the turntable body 110 is provided with a pin hole, and the pin 142 is engaged in the pin hole.

[0094] Specifically, a guide portion 144 may be provided on the locking mounting base 143. The guide portion 144 has a guide groove 145, and the pin 142 is located in the guide groove 145. The guide groove 145 can limit and guide the installation of the pin 142.

[0095] In order to facilitate the assembly of the pin 142 and the pin hole, the end face of the pin 142 near the turntable body 110 can be set to a conical shape, which makes it easier to be locked in the pin hole.

[0096] It should be noted that there is no further limitation on the number of pins 142 and pin holes. The specific number can be set according to the actual situation. In this embodiment, four pins 142 and four pin holes are set as an example for illustration. The four pin holes are evenly distributed on the turntable body 110.

[0097] The structure of the slewing assembly of the bogie turntable is described below:

[0098] Reference Figure 7As shown, the rotary assembly 120 may include a rotary motor 121, a rotary mounting base 122, and a rotary component 123. The rotary mounting base 122 is connected to the pit 200. The second end of the rotary assembly 120 is the end of the rotary mounting base 122 connected to the pit 200. The rotary motor 121 is mounted on the rotary mounting base 122.

[0099] The rotating component 123 is connected between the rotary motor 121 and the turntable body 110. The first end of the rotary assembly 120 is the end where the rotating component 123 is connected to the turntable body 110. The rotary motor 121 and the rotating component 123 are electrically connected. The rotary motor 121 drives the rotating component 123 to rotate the turntable body 110.

[0100] For example, the connection method between the rotary mounting base 122 and the pit 200 is not limited, and can be set according to actual needs. In addition, the rotary motor 121 and the rotary component 123 can be electrically connected by wire, or the rotary motor 121 and the rotary component 123 can be electrically connected by wireless means.

[0101] Specifically, in this embodiment, the rotating component 123 can be a slewing bearing of a meshing gear set, bearing and transmitting the axial and radial loads and overturning moment of the turntable body 110, and providing rotational power for the turntable body 110; the rotary motor 121 can be a servo motor, which can provide sufficient rotational power and precise alignment angle for the rotating component 123.

[0102] Additionally, it should be noted that the rotary component 120 in this application embodiment can be a split structure. For example, the rotary component 120 in this application embodiment adopts an upper and lower fastening method, which facilitates installation and maintenance operations, reduces the difficulty of multi-directional adjustment, and reduces the workload of installation and maintenance.

[0103] In one possible implementation, refer to Figure 5 and Figure 6 As shown, it may also include a support wheel assembly 150, one end of which is connected to the turntable body 110, and the other end of which abuts against the pit 200.

[0104] Specifically, the support wheel assembly 150 is mainly installed on the outer periphery of the turntable body 110, so as not to interfere with the normal rotation of the rotary assembly 120.

[0105] The support wheel assembly 150 consists of multiple support wheels 151. For example, the support wheel assembly 150 may include four, six, eight, or more support wheels 151. In this embodiment, the support wheel assembly 150 comprising eight support wheels 151 is mainly used as an example for description. The eight support wheels 151 are evenly distributed on the outer periphery of the turntable body 110.

[0106] With this configuration, when the vehicle and bogie 400 pass through the turntable body 110, the lower part of the support wheel 151 and the pit 200 are in effective contact, which helps to prevent the outer ring of the turntable body 110 from sinking and ensures the normal rotation of the turntable body 110.
